Description

Die Erfindung betrifft eine quaderförmige Karton/Kunststoff-Verbundpackung zur Verwendung in einer Vorrichtung zum Sterilisieren von quaderförmigen Karton/Kunststoff-Verbundpackungen in einem Autoklaven, wobei die aus Produkt und Verpackung bestehenden Packungen einer Wärmebehandlung bei einer bestimmten Temperatur über eine bestimmte Dauer unterzogen wird, wobei das Produkt aus einer Flüssigkeit und stückigen Anteilen besteht und wobei im Inneren des Autoklaven Einrichtungen zum rotatorischen Antrieb der Packungen um eine Drehachse vorgesehen sind, wobei eine Mehrzahl von in parallelen Reihen dicht benachbarter Packungen (P) auf Tragböden angeordnet sind und wobei eine Mehrzahl von mit Packungen (P) bestückten Tragböden übereinander angeordnet und in ihrer gegenseitigen Lage fixiert sind.The invention relates to a parallelepiped carton / plastic composite package for use in an apparatus for sterilizing parallelepiped carton / plastic composite packages in an autoclave, wherein the packages consisting of product and packaging are subjected to a heat treatment at a certain temperature for a certain duration, wherein the product consists of a liquid and lumpy portions and wherein inside the autoclave means are provided for rotationally driving the packages about an axis of rotation, wherein a plurality of closely spaced parallel rows of packages (P) are arranged on trays and wherein a plurality of Packings (P) equipped trays are arranged one above the other and fixed in their mutual position.

Es ist seit langem bekannt, portioniert abgepackte Produkte wie beispielsweise Lebensmittel zur Haltbarmachung einem so genannten Autoklavierprozess zu unterziehen. Hierbei werden beispielsweise Konservendosen, in welche zuvor Lebensmittelprodukte abgepackt worden sind in einem Autoklaven für eine bestimmte Dauer einer bestimmten Temperatur ausgesetzt, um die im Produkt bzw. der Dose befindlichen Keime zuverlässig abzutöten. Konservendosen haben sich für den genannten Zweck insbesondere deshalb bewehrt, weil sie unempfindlich gegenüber den in einem Autoklaven herrschenden Bedingungen (hohe Temperatur, hohe Feuchte, hoher Druck) sind.It has long been known to undergo portioned packaged products such as foods for preservation a so-called autoclaving process. Here, for example, cans, in which previously food products have been packaged in an autoclave for a certain duration of a certain temperature exposed to reliably kill the germs in the product or the can. Food cans have been reinforced for the purpose mentioned in particular because they are insensitive to the in one Autoclave conditions (high temperature, high humidity, high pressure).

Werden Lebensmittel oder andere zu sterilisierende Produkte jedoch nicht in Konserven sondern in anderen Verpackungen auf den Markt gebracht so muss - mit relativ hohem Aufwand - zunächst die Verpackung sterilisiert werden, dann das Produkt unter sterilen Bedingungen in die Verpackung gefüllt werden und schließlich die Verpackung aseptisch geschlossen werden. Auf diese Weise hergestellte Karton/Kunststoff-Verbundpackungen sind in der Lage, Produkte wie beispielsweise Milch oder püriertes Gemüse über einen längeren Zeitraum aufzunehmen.However, if food or other products to be sterilized are not put on the market but in other packaging, the packaging must first be sterilized at relatively high cost, then the product must be filled into the packaging under sterile conditions and finally the packaging must be closed aseptically become. Cardboard / plastic composite packages made in this way are able to absorb products such as milk or pureed vegetables for a longer period of time.

Aus der EP 1 382 353 ist eine Vorrichtung zum Sterilisieren von Karton/Kunststoff-Verbundpackungen bekannt. Dabei werden mit Hilfe eines Rotationsautoklavprozesses zum Sterilisieren von Lebensmitteln die Verbundpackungen in einem Autoklaven währen der Behandlung derart bewegt, dass eine ständige Durchmischung des Packungsinhaltes während des Autoklavierprozesses gewährleistet ist. Hierbei unterliegen die Packungen einer erhöhten Beanspruchung durch Feuchtigkeit, Druck und Temperatur, insbesondere an ihren Nähten und Schnittkanten.From the EP 1 382 353 a device for sterilizing cardboard / plastic composite packages is known. In doing so, by means of a rotary autoclave process for sterilizing foodstuffs, the composite packagings are moved in an autoclave during the treatment in such a way that a constant mixing of the contents of the pack during the autoclaving process is ensured. In this case, the packs are subject to increased stress due to moisture, pressure and temperature, in particular at their seams and cut edges.

Des Weiteren ist ein sterilisierbares Verbundmaterial aus der WO 02/090206 A1 bekannt. Dort werden die einzelnen Schritte zum Herstellen einer Karton/Kunststoff-Verbundpackung aufgeführt. Eine quaderförmige Packungsform wird dort nicht offenbart. Darüber hinaus enthält WO 02/090206 A1 nichts, was auf eine rotierende Behandlung beim Autoklavieren hindeuten könnte.Furthermore, a sterilizable composite material from the WO 02/090206 A1 known. There, the individual steps for producing a cardboard / plastic composite package are listed. A cuboidal packing form is not disclosed there. In addition it contains WO 02/090206 A1 nothing that could indicate a rotary treatment during autoclaving.

Davon ausgehend liegt der vorliegenden Erfindung die Aufgabe zu Grunde, die eingangs genannten Packungen so auszugestalten und weiterzubilden, dass eine zufrieden stellende Sterilisation einer größeren Anzahl von Packungen ermöglicht wird, ohne dass die Packungen verformt werden, dass ihr Druckbild beschädigt wird oder dass Wasser bzw. Dampf in sie eindringt.Based on this, the object of the present invention is to design and further develop the packs mentioned above in such a way that satisfactory sterilization of a larger number of packs is possible without deforming the packs, damaging their printed image or causing water or Steam penetrates her.

Diese Aufgabe ist dadurch gelöst, dass der Karton zur Verminderung des Wassereintritts mittels Leim hydrophobiert ist und dass die eingesetzte Leimmenge zwischen 1 und 4 kg/t trockenen Faserstoffs liegt.This object is achieved in that the cardboard is hydrophobicized to reduce the ingress of water by means of glue and that the amount of glue used is between 1 and 4 kg / t of dry pulp.

Eine weitere Lehre der Erfindung sieht vor, dass die Dichte des verwendeten Rohkartons im Bereich von 680 bis 860 kg/m3 liegt. Vorzugsweise beträgt der Mahlgrad der für die Packung verwendeten Kartonfasern 15 bis 35 SR. Ein solches Material kann den im Autoklaven herrschenden extremen Bedingungen gut standhalten.Another teaching of the invention provides that the density of the raw board used is in the range of 680 to 860 kg / m 3 . Preferably, the degree of grinding of the paperboard fibers used for the package is 15 to 35 SR. Such a material can easily withstand the extreme conditions prevailing in the autoclave.

Gemäß einer weiteren Ausbildung der Erfindung sind die Oberflächen der Packungen hydrophob bedruckt und/oder ist der Druck durch eine transparente Kunststoffschicht geschützt. Eine Beschädigung des Druckbildes durch Abrieb und Abplatzen oder Verfärben ist mit dieser Ausgestaltung zuverlässig ausgeschlossen.According to a further embodiment of the invention, the surfaces of the packs are printed hydrophobic and / or the pressure is protected by a transparent plastic layer. Damage to the printed image due to abrasion and spalling or discoloration is reliably excluded with this design.

Eine besonders gute Sterilisation lässt sich dann erreichen, wenn die Füllmenge der verwendeten Packungen so gewählt ist, dass in ihrem Inneren eine Gasblase von 2 bis 30 % des Nennvolumens der Packung vorhanden ist. Dadurch und die im Produkt befindlichen stückigen Anteile findet beim Rotieren im Autoklaven eine gleichmäßige und ständige Durchmischung des Packungsinhaltes statt. Dies führt zu deutlich kürzeren Behandlungszeiten, was eine weitere Schonung der verwendeten Packungen nach sich zieht. Als Gas lässt sich in bekannter Weise beispielsweise Stickstoff einsetzen.Particularly good sterilization can be achieved if the filling quantity of the packings used is selected so that a gas bubble of 2 to 30% of the nominal volume of the pack is present in its interior. As a result, and the lumpy fractions in the product takes place during rotation in the autoclave, a uniform and constant mixing of the contents of the package. This leads to significantly shorter treatment times, which entails further protection of the packs used. As a gas can be used in a known manner, for example, nitrogen.

Eine weitere Ausbildung der Erfindung sieht vor, dass die Schnittkanten der Packungen zusätzlich verpresst sind. Während die Packungsoberflächen durch die PP-Beschichtung und/oder die hydrophobe Bedruckung relativ gut vor Eindringen von Feuchtigkeit geschützt sind, sind die "offenen" Schnittkanten im Bereich der Nähte besonders gefährdet. Aus diesem Grunde verhindert eine zusätzliche Verpressung das Eindringen von Dampf oder Feuchtigkeit in das Verbundmaterial.A further embodiment of the invention provides that the cut edges of the packs are additionally pressed. While the packaging surfaces are relatively well protected against the ingress of moisture by the PP coating and / or the hydrophobic printing, the "open" cut edges in the region of the seams are particularly endangered. For this reason, an additional compression prevents the Penetration of steam or moisture into the composite.

Zum Abfangen des Sauerstoffanteils im Karton/Kunstoff-Verbundmaterial können nach einer weiteren Lehre der Erfindung Scavenger eingesetzt werden. Die Verwendung solcher "Sauerstofffänger" in Packstoffmaterial ist für sich bereits bekannt.To intercept the oxygen content in the cardboard / plastic composite material scavengers can be used according to another teaching of the invention. The use of such "oxygen scavengers" in packaging material is already known per se.

Die gezeigte Vorrichtung zum Sterilisieren von quaderförmigen Karton/Kunststoff-Verbundpackungen P besteht, wie aus den Fig. 1 bis 3 ersichtlich, zunächst aus einem Rahmengestell 1, in welches eine Mehrzahl von Einsatzblechen 2 eingesetzt sind. Damit die Einsatzbleche 2 beim Rotieren des Rahmengestells 1 nicht aus diesem herausfallen, besitzt das Rahmengestell 1 einen arretierbaren Deckel 3.The device shown for sterilizing cuboid cardboard / plastic composite packages P consists, as shown in Fig. 1 to 3 can be seen, first from a frame 1, in which a plurality of insert plates 2 are used. Thus, the insert plates 2 do not fall out of this during rotation of the frame 1, the frame 1 has a lockable lid. 3

Das Rahmengestell 1 ist über Achsen 4 in auf einem Grundrahmen 5 befindlichen seitlichen Stützen 6 drehbar gelagert. Zum Aufbringen des notwendigen Drehmoments ist die in der Fig. 2 links angeordnete Drehachse 4 endseitig mit einem Kettenrad 7 versehen, welches über eine gestrichelt dargestellte Kette C mit einem weiteren Kettenrad 8 sowie einem nur in Fig. 1 angedeuteten Spannrad 9 mit einer Antriebswelle 10 verbunden ist, welche endseitig eine Klauenkupplung 11 aufweist, die beim Hineinfahren in den Autoklaven A in Richtung des nicht näher bezeichneten Pfeils mit einer entsprechenden Kupplung eines Antriebsmotors (nicht dargestellt) in Wirkverbindung tritt.The frame 1 is rotatably supported by means of axles 4 in lateral supports 6 located on a base frame 5. To apply the necessary torque is in the Fig. 2 provided on the left with a sprocket 7, which has a dashed chain C with another sprocket 8 and a only in Fig. 1 indicated tensioning wheel 9 is connected to a drive shaft 10, which has a dog clutch 11 at the end, which enters into the autoclave A in the direction of unspecified arrow with a corresponding coupling of a drive motor (not shown) in operative connection.

Zum Erleichtern des Beschickungsvorganges verfügt der Grundrahmen 5 an seiner Unterseite über Führungsschienen 12, die zur Führung entlang an einer Basis B des Autoklaven A freidrehend befestigten Rollen R dienen, wie dies aus den Fig. 1 und 2 deutlich hervorgeht.To facilitate the loading process, the base frame 5 on its underside on guide rails 12 which serve to guide along a base B of the autoclave A freely rotatably mounted rollers R, as shown in FIGS Fig. 1 and 2 clearly shows.

Aus Fig. 2 ist ferner zu entnehmen, dass der Deckel 3 mittels eines Gelenks 13 am Rahmengestell 1 befestigt ist und mit Hilfe von zwei Verschlüssen 14 in seiner geschlossenen Stellung arretiert werden kann. Das geschlossene Rahmengestell 1 lässt sich dann im Inneren des Autoklaven A um die Rotationsachse 4 drehen; der zugehörige Schwenkkreis S ist in Fig. 1 strichpunktiert dargestellt.Out Fig. 2 It can also be seen that the lid 3 is fixed by means of a hinge 13 on the frame 1 and can be locked by means of two closures 14 in its closed position. The closed frame 1 can then be rotated inside the autoclave A about the axis of rotation 4; the associated pivoting circle S is in Fig. 1 shown in phantom.

Aus Fig. 3 geht nun hervor, dass jedes Einsatzblech 2 von denen nur das oberste bei aufgeklapptem Deckel 3 sichtbar ist, über einen umlaufenden Rahmen 15 verfügt, der die seitliche Begrenzung einer Vielzahl erfindungsgemäßer Packungen P bildet. Damit die Packungen P in gleichmäßigen Längsreihen hintereinander und auf ihren Schmalseiten liegend innerhalb des Einsatzbleches 2 angeordnet werden können, verfügt jedes Einsatzblech 2 über die gesamte Länge des Einsatzbleches 2 verlaufende Stegbleche 16, die eine seitliche Begrenzung für die benachbarten Packungsreihen darstellen.Out Fig. 3 now it is apparent that each insert sheet 2, of which only the top is visible when the lid 3 is opened, has a peripheral frame 15, which forms the lateral boundary of a plurality of inventive packs P. So that the packs P can be arranged in uniform longitudinal rows one behind the other and lying on their narrow sides within the insert plate 2, each insert plate 2 has over the entire length of the insert plate 2 extending web plates 16, which constitute a lateral boundary for the adjacent rows of packages.

Der genaue Aufbau der Einsatzbleche 2 lässt sich aus Fig. 4 entnehmen, in der der obere Teil eines Paketes von Einsatzblechen 2 aus Fig. 2 im Querschnitt in Richtung der Pfeile IV-IV gezeigt ist. Hier ist zunächst zu erkennen, dass der Rahmen 15 der Einsatzbleche 2 hohl ausgebildet ist und so weit hinunter reicht, dass er gewissermaßen gleichzeitig einen oberen "Deckel" für die unter ihm angeordneten Packungen P darstellt. Der Deckel 3 besitzt daher an seiner Unterseite die gleiche Form. Ferner ist erkennbar, dass die Stegbleche 16 so angeordnet sind, dass sie nach oben spitz zulaufen, unten jedoch jeweils eine Packungsbreite definieren. Ein solcher Aufbau ermöglicht eine leichte seitliche Bewegung der Packungen P beim Drehvorgang im Autoklaven A.The exact structure of the insert sheets 2 can be Fig. 4 remove, in the upper part of a package of insert plates 2 from Fig. 2 in cross-section in the direction of arrows IV-IV is shown. Here it should first be recognized that the frame 15 of the insert plates 2 is hollow and extends so far down that it effectively represents at the same time an upper "lid" for the packs P arranged below it. The lid 3 therefore has the same shape on its underside. Furthermore, it can be seen that the web plates 16 are arranged so that they taper upwards, but below each define a package width. Such a construction allows easy lateral movement of the packs P during the rotation process in the autoclave A.

Damit sich nun das Sterilisiermedium optimal auch im Bereich der Einsatzbleche 2 verteilen kann, weisen sowohl der Rahmen 15 als auch die Stegbleche 16 Ausnehmungen 17 auf. Der Boden 18 der Einsatzbleche 2 ist als Hohlboden ausgeführt, d. h. hier besteht aus einem oberen Boden 18A und einem unteren Boden 18B wie in den perspektivischen Darstellungen gemäß Fig. 5 und Fig. 6 deutlich gezeigt. Diese Ausbildung hat den Vorteil, dass die geschlossenen Böden 18A, welche nicht mit Ausnehmungen oder Löchern versehen sind, eine optimale Abstützung der schmalen Längsseiten der erfindungsgemäßen Packungen P darstellen. Zur besseren Übersicht ist in Fig. 6 eine in das gezeigte Einsatzblech 2 eingesetzte Packung P dargestellt.So that the sterilizing medium can be optimally distributed in the area of the insert sheets 2, both the frame 15 and the web plates 16 have recesses 17. The bottom 18 of the insert sheets 2 is designed as a hollow floor, ie here consists of an upper floor 18A and a lower floor 18B as shown in the perspective views Fig. 5 and Fig. 6 clearly shown. This design has the advantage that the closed bottoms 18A, which are not provided with recesses or holes, represent optimal support of the narrow longitudinal sides of the packs P according to the invention. For a better overview, see Fig. 6 a pack P inserted into the shown insert 2 is shown.

Dadurch, dass oberhalb des gezeigten Einsatzbleches 2 ein weiteres Einsatzblech 2 bzw. der Deckel 3, welcher ebenfalls mit Schlitzen 3A versehen ist, die Packungsreihen nach oben hin begrenzen, erfolgt auch eine entsprechende Abstützung bei der Rotation des Rahmengestells 1. Die Schlitze 3A sind, wie aus Fig. 3 hervorgeht, dazu genau oberhalb der Stegbleche 16 angeordnet. Die Höhe der Einsatzbleche 2 ist dabei so gewählt, dass zwischen dem Boden 18B eines Einsatzbleches 2 und den darunter befindlichen Oberflächen der Packungen P bei Beladetemperatur ein schmaler Luftspalt G vorhanden ist, wie aus Fig. 4 hervorgeht.Due to the fact that above the illustrated insert 2 another insert plate 2 or the cover 3, which is likewise provided with slots 3A, delimit the rows of packages at the top, there is also a corresponding support during the rotation of the frame 1. The slots 3A are like out Fig. 3 emerges, arranged just above the web plates 16. The height of the insert sheets 2 is chosen so that between the bottom 18 B of an insert plate 2 and the underlying surfaces of the packages P at loading temperature, a narrow air gap G is present, as shown Fig. 4 evident.
